We went through the same thing with my daughter. We tried everything to try to get her back to sleep without feeding her and nothing worked. The whole house ended up being up for 2-3 hours until she finally cried herself to sleep. After a few nights of this and having to be at work in the morning, I was exhausted and gave in & fed her a small bottle. We were all back in bed & sleeping in about 10 minutes. The nurses at the pediatricians office insisted that I was starting a habit that would result in her needing to eat in the middle of the night forever. The pediatrician himself disagreed and said, "do whatever you need to do so your family can sleep". We followed his advice, the bottles in the night didn't last long (probably a growth spurt) and she does not need to eat during the night now. I would suggest doing whatever works for your family & your baby. Good Luck!!
